replacement ecu

[sxsuniverse]

I have a bad ecu so I ordered one of ebay it's going in a 2015 ranger the ecu coming is from a 2015 rzr do I have to reflash the ecu and if I do can I use any stock file for a 2015 ranger 900 ho?

You will need to completely rewrite it and HPtuners will not do that. Likely will need to take vehicle with the replacement ecu to the dealer, but they might not touch it since it is used. I can help, but you would need to ship it to me.

so whats needs to be used to do that? kess3?

Yes, something like Kess V3, or older Ktag, Bitbox with a tactrix and the correct module, AOX tool, etc.
